HazMat Fee

An item is classified as a dangerous good if our website displays Hazardous Material (HazMat) information for it. There is a HazMat shipping fee for each item that qualifies as a dangerous good, except in the following scenarios:

The shipment is processed through FedEx Ground under the Limited Quantity option.

Each bottle is packed as an Excepted Quantity, with a maximum of 1g for items in class 6.1 packing group I or II, and up to 25g for all other hazardous materials.

If shipping is charged to your FedEx account, the HazMat fee will be billed directly by the courier. Otherwise, the fee will be included on your invoice. To help you avoid the HazMat fee, we can package a 5g order of a class 6.1 packing group I or II material as five separate 1g units, and a 100g order of any other dangerous good as four 25g units. This packaging adjustment will be made unless you instruct otherwise on your purchase order. Below, you will find the fee schedule from FedEx for handling hazardous materials.

Description

Dimethyl difluoromalonate is a highly reactive fluorinated diester featuring two geminal fluorine atoms on a malonate backbone. This electron-deficient structure enables efficient Michael additions and nucleophilic substitutions under mild conditions, serving as a key building block in synthetic organic chemistry for introducing fluorinated motifs with high regiocontrol.

Application

Dimethyl difluoromalonate serves as a versatile fluorinated building block in synthetic organic chemistry, enabling the efficient introduction of difluoromethylene units into target molecules. Its stabilized α,α-difluoro ester functionality facilitates nucleophilic addition and Michael-type reactions with high chemoselectivity. The compound exhibits robust bench stability and compatibility with common functional groups, simplifying purification and scale-up. It functions effectively in the synthesis of fluorinated heterocycles and carbocyclic scaffolds relevant to medicinal chemistry and agrochemical development.
